Why isn't this working??

I can't complete this challenge! Whats wrong with the code right here?

struct.swift
struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String) {
        self.description = description
    }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

    func calculateTaxes(percentage: Double) -> Double{
    return ("\(self.amount)*\(percentage/100)")
    }

}

Your function is expecting a Double and you are returning a String instead:

    // Function returns Double
    func calculateTaxes(percentage: Double) -> Double{
        // This is a String
        return ("\(self.amount)*\(percentage/100)")
    }

 // Fixed
    func calculateTaxes(percentage: Double) -> Double{
       return (self.amount)*(percentage/100)
    }
